PURPOSE: To improve the surface appearance, dimensional stability, impact resistance and moldability of a molding by compounding a specified polyamide resin, an inorganic fibrous filler and an inorganic particulate filler. CONSTITUTION: 100 pts.wt. polyamide resin (A) consisting of 85-99wt.% polyamide component comprising polyhexamethyleneadipamide with a relative viscosity in sulfuric acid at 25 deg.C of 2.0 to 3.0 and a polyamide resin comprising polycaproamide which is obtained fromε-caprolactam and has a relative viscosity in sulfuric acid at 25 deg.C of 3.0-4.0 is compounded with 5-70 pts.wt. of at least one inorganic fibrous filler (B) selected from among glass fibers, carbon fibers, etc., 9-70wt.% inorganic particulate filler (C) selected from among wollastonite, calcined kaolin, etc., and a color master batch in an amount of 1.0-3.5 pts.wt. based on 100 pts.wt. resin composition. The obtained mixture is melted and kneaded to give the polyamide resin composition having a weight ratio of component B to component C of (0.4 to 0.65):1.
